Excel library for process calc's including distillation

[mderra]

in my experience Lee Kesler gives indeed accurate results for HC mixtures,
not to use for other chemicals, though.

[carlo.stenali]

in some cases you can select the Lee Kesler Plocker model
which has been designed to handle very asymmetric mixtures

does someone know where to find good VLE data sets for C2-H2O, C3-H2O, H2S-H2O etc.

I wish to use PRODE PROPERTIES to regress temeperature dependent BIPs for these pairs...

thanks a lot

where is the link??

[carlo.stenali]

mohammed,
look for PRODE PROPERTIES with Google
or go directly to
'http://www.prode.com/en/properties.htm'

thank you Carlo, got it.

Does the distillation column in PRODE PROPERTIES allow to solve VLL (vapor-liquid-liquid) ?
I have a three phase distillation to simulate.

[carlo.stenali]

matrenel,
yes, the column model in PRODE PROPERTIES can solve

vapor-liquid
vapor-liquid-liquid
liquid-liquid

separations, you can specify reflux,
heat, purity, recovery etc.

Matrenel,
yes, I have solved both VL and VLL columns with PRODE PROPERTIES,
(no direct experience with LL but that depends from my field of application)

[matrenel]

thanks Carlo and cbadia,
I was in contact with PRODE, a commercial licence is required for the vapor-liquid-liquid column,
actually the free version 1.2b does include only the vapor-liquid column,
I decided to upgrade and I have tested the VLL column,
no problems to solve my specific application.
